How To Tell If Motherboard Is Dead?

How To Tell If Motherboard Is Dead?.

If your motherboard is lifeless, the PC gained’t energy on in any respect. This means the PSU fan gained’t spin, and the motherboard LEDs gained’t mild up.

These are the primary indicators, however don’t conclude that your motherboard is lifeless primarily based on simply these, although. Power provide points typically result in equivalent signs.

To correctly check whether or not your motherboard is lifeless, comply with the step-by-step troubleshooting course of I’ve described on this article.

Diagnosing a Dead Motherboard

A system with a lifeless motherboard will present little to no indicators of energy. But issues with the facility provide system (outlet, PSU, energy cables and connectors, and so forth.) also can trigger the identical end result.

So, begin by verifying that the parts are working high-quality. If you may swap them or check them on one other system, that may be the simplest technique. 

But if that’s not potential, use the next course of to check all the things by yourself: 

  1. Turn off the PSU change. Unplug the AC energy cable and PSU-to-motherboard connections.turn-off-psu-unplug-power-cord
  2. Reconnect all the things firmly and activate the PSU. Then, strive turning on the PC.
  3. Swap the AC energy cable together with your monitor’s energy wire (or every other recognized good wire).
  4. Try a completely different outlet too.
  5. Short the Power Switch pins (PW+ and PW-) on the motherboard with one thing like a flathead. This is to account for defective case energy buttons or connections.shorting-motherboard-power-switch-pins

If the PC doesn’t activate, you will need to test in case your PSU is flawed.

  1. Remove the PSU and motherboard from the case and place them on a non-conductive floor.
  2. Turn on the PC. If the motherboard was shorting resulting from unintended contact with the case, it ought to work now.
  3. Remove all of the PSU-to-motherboard connections. Use a PSU jumper or paperclip to begin the PSU. We’re testing it independently to test if the PSU was not beginning earlier resulting from Overcurrent safety.atx-connector-paperclip-test
  4. Finally, use a multimeter to check the voltage readings on the PSU connectors. A PSU tester may also work nice. Verify that the PSU is supplying correct voltage.psu-atx-connector-multimeter-test

If the PSU seems to be defective, quickly use one other suitable PSU together with your PC. If the system boots now, you recognize which element to switch.

However, if the PSU examined okay in Steps 3 and 4, your motherboard is most definitely lifeless. You might even discover seen indicators of harm (burnt sections from brief circuits, bulged/cracked capacitors, bent pins, and so forth.).

Ultimately, you’ll must borrow a board from somebody or take the PC to a restore skilled. I count on that the system will boot easily with a brand new motherboard, confirming that the previous board was certainly lifeless.

Can You Recover A Dead Motherboard?

Repair professionals typically get better lifeless motherboards by changing the broken parts. But this tends to be technical and costly.

In my expertise, individuals are often higher off buying a brand new motherboard as a substitute (resulting from elements like newer parts and warranties).

I’m more serious about recovering motherboards that may’t get previous POST (Power-On Self-Test) right here.

The BIOS catalogs all essential gadgets and prepares the system in addition throughout POST. If a core element (CPU, RAM, GPU, and so forth.) is defective, the system gained’t boot. Users typically misread this because the motherboard being lifeless

In this case, the followers and LEDs will energy on. Most importantly, you’ll wish to test the diagnostic indicators:

  • Beep Codes: If you’ve put in a buzzer on the motherboard, it would play sure sounds at startup. You can lookup the patterns on our website (e.g., 1 lengthy 2 brief beeps) to grasp what downside your system is dealing with.
  • Debug LEDs: If you see a pink or orange LED in your motherboard, get nearer and test the label. There needs to be 4 LEDs in your board to point RAM, CPU, show, and boot device points. 
  • POST Codes: Higher-end boards additionally embrace a small show that reveals hexadecimal codes. Once once more, you may lookup these codes on our website to grasp why your PC isn’t booting.

After checking these, you’ll notice that you simply don’t have to get better your lifeless motherboard as a result of it’s most likely working high-quality. Instead, you’ll be capable to determine the precise defective element and remedy the underlying downside.
